Flaring differences between R22 and R410a
Hi there, as the title suggests I'm curious to find out the major differences between flaring pipework for the two refrigerants R22 and R410a (for pipes 1/4 to 5/8 for domestic split systems). I've done plenty of work with R410a however have not dealt with flaring pipes for R22. Most R22 systems Ive dealt with have already been installed, and since I've been asked to re-install a working split (where the existing pipes were damaged during transport) I'd like to find out abit more. All I know is since there is a lower operating pressure with R22, the flare does not have to be as "deep" and the copper pipe does not to be as thick compared to pipework for R410a. Is a person able to use the R410a flaring block for R22 flares? Can the pipe to be flared be left more in the flaring block so the flare isnt as large? Thanks in advance
